Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.

Skogspolitik i Sverige

For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.

Undervisning av teorier kring livets uppkomst och evolution i ämnet biologi på grundskolans senare år och gymnasiet. : Kan misstolkning av läroplanerna  leda till konflikter kring undervisning om evolution?

Recent studies indicate that teaching the theory of evolution in Swedish secondary schools is not as uncontroversial as expected considering that Sweden is often described as one of the World?s most secularzied countries. A recent study indicates that Swedish teachers have a varity of tactics to avoid coming in conflict with their students or even parents of students that believe they have a rightto dictate how evolution should be taught. This study had fourmain aims; the first being to analyse both the previous curriculum and the new to see how the teaching of evolution is adressed, and if any changes have been made in the curriculum. The second being to look into how teachers interpret the curriculumand if they have noticed any changes in the new curriculum which have had an affect on their teachingmethods? The third being if teachers have met resistance when they teach evolution and the origins of life, and if so, how do they deal with these conflicts? The fourth and final aim of this study was to see if instances of conflict are on the rise as indicatedin the literature.The results of this study indicate that there has been no siginificant changes made in the curriculum with the exceptionthat the new curriculum is more clear and precise as to what teachers are expected to teach and that pseudoscience, such as intelligent design, has no place in science classroomsexcept when teachingthe philosophy of science.

Vår nådiga vilja och befallning : Kungl. Maj:ts brev till landshövdingen på Gotland 1735

This is a study of the letters from His Majesty the King to the county governor of Gotland in 1735. In the Age of Liberty the king had limited power. Royal decisions were made with the Council of the Realm where the King only had the advantage of having two votes and a casting vote. Furthermore, the Council had to act according to the decisions of the Estates of Parliament, if at least three of the four Estates were in agreement. The duties of the county governor were set out in a detailed instruction of which the most recent version was issued in 1734.

E-learning ? en utbildningsmetod och dess nytta

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing. The study is founded on a qualitative method that is based on a case study in eight companies.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

En kombinerad Organisk Rankinecykel och värmepump integrerat med ett fjärrvärmesystem : Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet

The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

The parenthood of adoptive mothers ? a qualitative study about self experiences and motives of single adoptions

The primary purpose of this essay is to study and describe what single adoptive mothers believe to be significant motives when considering adoption. This essay also describes how single adoptive mothers experience parenthood in relation to their expectations. The theoretical perspectives applied to analyse the empirical data are existentialism, the identity making process, and social constructionism. The method of this study is qualitative based on seven interviews. The material has been analysed by condensed meaning units and themes with a phenomenological approach.

Cultural influences on perceived information structures and assortment varieties - a comparative study of Middle Eastern and Swedish consumers

The purpose of this study was to investigate and compare how and why consumers of different ethnic backgrounds value and prioritize product attributes among food in certain ways. We expected to find culturally bound attitude differences and our aim was to relate those to, and challenge, present knowledge of information structures. Consequently, we also aimed to use this new knowledge of attribute attitudes in connection to assortment variety theory, as attributes constitute important motives to how consumers perceive variety. A theoretical framework was constructed to suit our purpose and function as an analytical tool, consisting of Culture perspectives, Information structures (product attributes), and Assortment variety. In this thesis we focused on attitudes and consumer perspectives and excluded actual behaviour and the retailing perspective.

Chefers och medarbetares uppfattning om ett gott ledarskap

Leadership is a well-known phenomenon in today?s world and researchers have developed multitudes of theories with different assumptions about what leadership is and what implications it has. Models of different kinds of leadership have been presented and researchers are constantly working on trying to find a definition of great leadership. Our thought was however that because every human being is unique it would be naïve to presume that all people hold the same perception about what constitutes good leadership. Although we believed that every person defines good leadership in his/her own way we also believed that there could be similarities to be found between illustrations generated from people with comparable organizational positions.

Mångbruksplan Äspinge 2:2

This plan of multiple-use is made on the private owned forestproperty Äspinge 2:2 in the middle of Skåne. The term ?multiple-use? came to Sweden in the beginning of the twentieth century and has slowly grown until about 30 years ago when the laws of nature conservation and sustainability was written into the forest law. The so called ecoturism got more and more popular and people began to seek space and silence in difference to the life in the highly populated areas. This also encouraged foreign tourists to come to Sweden. Mostly danish, german, and dutch people.

Del projekt inom ClampCal - Utvärdering av mätmetoder för temperatur, viskositet och densitet samt röregenskaper

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

Objektdetektering i SAR- och IR-bilder

This report treats detection in IR-pictures taken from airplanes over the ground. The detection is divided in two parts. First there is a detection with filterkernels with the task to point on targets and objects that look like targets. The second part is a discriminator that demands more calculations and has the task to sort out the false alarms from the discriminator. Both the detector and the discriminator contain thresholds thats been trained from trainingsets of data.

Spela roll: filmregissör : Om tolkning, kommunikation och duktiga flickor

This text deals with the shooting of a movie comedy. The author of this text was script writer as well as director. The film was extremely dependent upon the interpretation of the role of the leading female character, but the director and the leading actress, in spite of their willingness to cooperate, were unable to understand each other, and no creative meeting ever occurred.The film dealt, in amused distance, with male and female strategies and shortcomings, but the lack of understanding between the director and the leading actress caused the subtleties of the text disappear, so that when the film was ready it was possible to interpret it in a way that partly opposed its intentions.From the director?s point of view different aspects of the situation are investigated: what could she /should she have done? What are the obstacles for a better understanding? Is ?understanding? dependant only upon that which is verbal? Should the director not only be a director but also a kind of therapist? What is professional and what is private? Could a director who wasn´t also the script writer have seen other solutions? And how does it affect you as a female director never to have role models, only a very clear idea of what you don?t want your professional role to look like.The director thought she was being constantly compromising, but finds out she was not, she had only a different, and in appearance, friendly but manipulative strategy in trying to reach her goal: that of enforcing and implementing her personal interpretation of the script. The role of director is also a role, and must be played.
